This is a typical scam. The common means of this kind of fraud is to induce you to "register your personal information" and "sign a contract" in the name of winning a prize, making a loan, handling a card, etc. And then lie to you. If you refuse, the swindler will tell you that you have been charged with unwarranted charges such as breach of contract (pretending to be a court), falsely claiming that you will be issued with a subpoena, and even taking coercive measures to scare you into paying the so-called liquidated damages, termination payments, settlement payments, security deposits, etc.
